I'm getting this error after adding checking Allow Signups to an event.

Database error in vBulletin 3.6.7:

Invalid SQL:

		SELECT	ea.userid, ea.response, ea.signupname, ea.comment, ea.signup_date,

I've tried uninstalling the product and reinstalling, same issue. I can add events fine, it only happens after checking signups, and then i can't even select the event without getting this error.
